REPLACEMENT PWA (TIMER BOARD) - MODELS WHES30, WHES33 & WHESLE
IMPORTANT: Be sure the valve cam indicates “service” position when replacing the
PWA, to assure both valve and timer are oriented, or timed, to the same cycle. If the
valve is not in service position, see step 8 below.
NOTE: When installing the PWA on the faceplate, use care not to twist the circuit
board, or force it onto the mounting pegs. Twisting could damage the printed cir-
cuits, or break the LED glass.
After installing the PWA, when the transformer is plugged into the electrical outlet,
model code LE30, LE31, LE33 or LE28 (take note of which) will be shown for a few
seconds in the faceplate display. Then, 12:00 PM and the words “CURRENT TIME”
begin to flash. Determine the correct model code for your softener in steps 1 and 2,
below. If the PWA’s preset model code is not correct, you must perform steps 3-5
before setting the clock (steps 6-9). If the code is correct, you may skip steps 3-5.
DETERMINE THE CORRECT MODEL CODE:
1. Open the salt cover of your softener and find the model number
on the decal just below the cover.
2. Using the table above, determine the correct model code.
SET THE MODEL CODE:
3. Press and hold the PROGRAM button for several seconds. First
the display will change to show “TURBINE”, then after several
more seconds the model code (LE30, LE31, LE33 or LE28) will
flash. Release the PROGRAM button.
4. Press the
r UP or s DOWN buttons to change the model code.
5. With the correct model code flashing, press the PROGRAM but-
ton to return to the “CURRENT TIME” display.
SET THE CLOCK:
NOTE: If the words “CURRENT TIME” do not show in the display,
press the PROGRAM button a few times, as needed, until
they do.
6. Press the r UP or s DOWN buttons to set the present time.
Up moves the display ahead; down set the time back. Be sure
AM or PM is correct.
7. Program the water softener following the instructions in your
owner’s manual.
8. If the valve is not in the service position, press the RECHARGE
button and hold for 3 seconds to start a recharge. When the gear
stops turning, press the RECHARGE button until the flashing
word “RECHARGE” is no longer shown in the display (this may
have to be done several times)
9. The valve and PWA should now be in their correct positions.

STATUS LIGHT
(Feature Upgrade on Models WHES30 & WHES33)
When the water softener is connected to electrical
power, the status light on the control panel will oper-
ate as follows:
= Light flashing slowly, along with the salt level
indicators in the display - The salt monitor sys-
tem indicates a low salt level and needs to be set.
See “Set Salt Level” in your owner’s manual.
= Light flashing slowly, along with the words
“SCHEDULED CLEAN” in the display - Four
months have elapsed on the system’s timer since
start up or the last reset. This is a reminder to use
Whirlpool™ WHE-WSC Water Softener Cleanser
three times a year. To reset the timer, press any
button on the control panel and the flashing words
will disappear. The status light will stop flashing,
unless the system is also low on salt (see above).
= Light flashing rapidly, with “CURRENT TIME”
shown in the display and the clock flashing
slowly - The present time needs to be set, either
during initial start up or after a long power outage.
See “Set Time of Day” in your owner’s manual.
= Light flashing rapidly, with “Err” shown in the
display - The electronic self-diagnostics have
detected a problem. See “Troubleshooting” in your
owner’s manual.
= Light on steady (not flashing) - The system has
power applied and does not require any attention.
